Work in small areas, starting in the middle and work toward the leading, and trailing edges, alternating sides. If you see wrinkles develope as you pull, heat those first. I find it easiest to use a heat gun for this. I only leave about 1" overlap, I usually don't have help. If you leave to much, the covering will stick to itself, then's when I start inventing new 4 letter words.

You may want to invest in a hot glove. fingers do get hot fast. Good luck Garry
